In the field of psychology, trait theory (also known as disposition theory) provides a way to study human personality. Proponents of this theory focus on measuring individual traits, which can be defined as habitual patterns of behavior, thinking, and emotion. According to this view, traits are relatively stable personality characteristics that vary across individuals over time (e.g., some people are extroverts while others are introverts) and are relatively consistent across situations, which also affects of individual behavior.
Traits are the opposite of states, which are more transient, and traits are generally considered components of personality.
Speaking of extroversion and introversion, this is an often cited category in trait theory. Extroverts are often described as social, lively, and enjoy interacting with others, while introverts are more self-reflective and enjoy time alone. This distinction affects their social style and is reflected in the way they handle social interactions.
American psychologist Gordon Allport was one of the early pioneers of trait research, and his early work is considered the beginning of modern personality psychology research. Allport called traits "dispositions" in his research and further divided them into "core traits", "central traits" and "secondary traits". Core traits are the traits that dominate an individual's behavior, while central traits such as honesty exist in varying degrees in everyone, while secondary traits only appear under specific circumstances.
With the progress of research, various alternative theories and scales have been gradually developed, including Raymond Cattell's 16PF questionnaire, Myers-Briggs Type Indicator (MBTI), etc. Two of the most popular methods currently are the Eysenck Personality Questionnaire (EPQ) and the Big Five model of personality traits. Eysenck proposed based on factor analysis that personality can be boiled down to three major traits: neuroticism, extraversion and psychoticism; while the five major personality traits believe that neuroticism, extraversion, openness, agreeableness and conscientiousness are enough to summarize personality .
Although both methods are tested using self-report questionnaires, they differ in the organization and number of factors. In particular, the Big Five personality trait model has been criticized for the positive correlations between factors. Eysenck argued that fewer major factors are better than more locally related factors. Therefore, the characteristics of psychopathy are key to distinguishing these two models.
When people with high scores in neuroticism are more likely to suffer from sleep and physical and mental illnesses, the Big Five personality model is better able to predict future psychological problems.
With cultural diversity, people's understanding and expression of traits may differ among different cultural groups. In this context, trait theory emphasizes the correlation between personal traits and selectively ignores cultural factors, allowing researchers to focus more on the internal connections of individual traits. Although traditional trait theory focuses on individuals, current research is gradually considering the impact of external factors on individual traits.
Whether you are an extrovert or an introvert, trait theory provides a powerful tool for understanding how you and others behave in social interactions. As your understanding of personality continues to deepen, how will you use this knowledge to improve your social style?
